Dinosaurs are a various institution of reptiles of the clade Dinosauria. They first seemed for the duration of the Triassic period, among 243 and 233.23 million years ago, despite the fact that the exact foundation and timing of the evolution of dinosaurs is the challenge of lively studies. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction occasion 201 million years ago; their dominance persisted via the Jurassic and Cretaceous periods. opposite genetic engineering and the fossil document both demonstrate that birds are modern feathered dinosaurs, having evolved from in advance theropods at some point of the past due Jurassic duration. As such, birds have been the simplest dinosaur lineage to live to tell the tale the Cretaceous–Paleogene extinction event 66 million years ago. Dinosaurs can therefore be divided into avian dinosaurs, or birds; and non-avian dinosaurs, that are all dinosaurs aside from birds. this newsletter deals broadly speaking with non-avian dinosaurs
Gigantoraptor is a genus of large oviraptorosaurian theropod dinosaur
Carcharodontosaurus is a genus of carnivorous carcharodontosaurid dinosaurs that existed during the Cenomanian level of the mid-Cretaceous duration.
Saltasaurus is a genus of titanosaurid sauropod dinosaur of the overdue Cretaceous duration of Argentina. Small amongst sauropods, even though nevertheless heavy by means of the standards of modern-day creatures, Saltasaurus become characterized by using a quick neck and stubby limbs.
Tsintaosaurus is a genus of hadrosaurid dinosaur from China. It became about 8.3 metres long and weighed 2.five tonnes. the type species is Tsintaosaurus spinorhinus, first defined by using chinese paleontologist C. C. younger in 1958.
Argentinosaurus is a genus of titanosaur sauropod dinosaur first determined by means of Guillermo Heredia in Argentina. The conventional call refers back to the united states of america in which it turned into located.
Megalosaurus is a genus of big meat-eating theropod dinosaurs of the middle Jurassic duration of Southern England.
Deinocheirus is a genus of large ornithomimosaur that lived at some point of the late Cretaceous around 70 million years ago.
Amargasaurus is a genus of sauropod dinosaur from the Early Cretaceous epoch of what is now Argentina.
Therizinosaurus is a genus of very large theropod dinosaurs. Therizinosaurus contains the unmarried species T. cheloniformis, which lived within the past due Cretaceous length, and changed into one of the ultimate and biggest.
Utahraptor is a genus of theropod dinosaurs. It contains a unmarried species, Utahraptor ostrommaysorum, that’s the most important-recognized family member Dromaeosauridae. Fossil specimens date to the top Barremian level of the early Cretaceous duration.
